The XCMD2115C12 is a miniature snap-action limit switch from the Telemecanique OsiSense XCMD family, built with a metal body and a thermoplastic roller lever actuator. Its contact rating of 240 VAC 1.5 Ampere and 250 VDC 0.1 Ampere defines the maximum load it can break — the AC figure handles typical control-circuit solenoids and contactor coils, while the DC figure is notably low, so inductive DC loads (brakes, valves) need careful current matching. The 1NO-1NC contact configuration gives a positive-break normally-closed channel for safety circuits per EN/IEC 60947-5-1, with the NC side mechanically linked to the actuator for forced opening. The IP66/IP67 and NEMA 4X/6P/12/13 enclosure means the switch body and the roller lever seal against hose-directed water and temporary submersion — suitable for washdown zones in food processing or outdoor conveyor transfers where a standard limit switch would wick moisture through the plunger seal. The 0.5 N positive-opening force and 0.1 N tripping force tell you the actuator requires deliberate contact to change state; it will not false-trigger from vibration on a running conveyor, but it also needs a positive cam or dog to overcome the 0.5 N reset spring.
The M12 5-pin male connector simplifies field wiring — no need to open the switch body for terminal connections, which keeps the IP66/IP67 seal intact. The overall dimensions of 1.18 Inch W x 0.63 Inch D x 1.97 Inch H fit into tight machine guarding frames where a full-size limit switch would overhang the mounting bracket. The actuation speed of 1.5 Meter/Sec is the maximum cam speed the roller lever can follow; faster cams risk the switch not fully resetting before the next cycle.
